When playing my FPS will randomly drop to around 22 FPS, the only way to fix it is to quit the game or to wait and sometimes it reverts. There is no way to consistently reproduce the issue, it happens randomly after playing for 5-30 mins usually. I normally run around 140 FPS on a survival world and it has only started since this update came out. This is on version 26.1.2 with no modifications consistent across different worlds and servers.
